Multi-layer metal article and method of making the same

Abstract

The multi-layer metal article (10) includes a metal base (12) formed from a first metal and at least one interlayer (14) formed on an upper surface (18) of the metal base (12). The at least one interlayer (14) is formed from a second metal having a greater hardness than a hardness of the first metal, thus increasing the hardness of the overall multi-layer metal article (10) when compared against the hardness of just the metal base (12). An outer coating layer (16) may then be coated on an upper surface (20) of the at least one interlayer (14). As a non-limiting example, the outer coating layer (16) may be a scratch-resistant material, thus increasing both the hardness and scratch resistance of the overall multi-layer metal article (10) when compared against those of just the metal base (12). The outer coating layer (16) may be transparent, partially transparent or opaque.
